MARC 21 Update No. 16: Full and Concise available online

Network Development and MARC Standards Office
Library of Congress

Update No. 16 (April 2013) is now available on the MARC website
(www.loc.gov/marc/). It is integrated into the documentation for each of
the Online Full and Concise formats that are maintained on that site --
the Bibliographic format, Authority format, Holdings format,
Classification format, and Community Information format. The documentation
includes changes made to the MARC 21 formats resulting from proposals
which were considered by the ALA ALCTS/LITA/RUSA Machine-Readable
Bibliographic Information Committee (MARBI), the Canadian Committee on
MARC (CCM) and the BIC Bibliographic Standards Group in January 2013.

The changes are indicated in red. Each format also has an appendix,"Format
Changes for Update No. 16 (April 2013)" that lists the changes that
comprise the update. The Web version of the formats is the official
version and is considered the start for implementation planning for MARC
21. Users are not expected to begin using the new features in the format
until 60 days from the date of this announcement: April 29, 2013. For more information about format documentation
see: http://www.loc.gov/marc/status.html.

Users who want a print version of changed fields will be able to print
them from the Format web pages (CDS does not sell a print version of
the update). Changes to the MARC 21 Formats that resulted from Update
No. 16 (April 2013) are displayed in red print. The "Format
Changes" appendixes described above also incorporate a print guide
following the list of changes, to facilitate easy printing.
